Your requirements could not be resolved to an installable set of packages. Problem 1 - illuminate/console 11.x-dev is an alias of illuminate/console dev-master and thus requires it to be installed too. - Conclusion: don't install illuminate/console dev-master (conflict analysis result) - Conclusion: don't install illuminate/console v10.16.1 (conflict analysis result) - Conclusion: don't install illuminate/console v10.24.0 (conflict analysis result) - Conclusion: don't install illuminate/console v10.25.0 (conflict analysis result) - Conclusion: don't install illuminate/console v10.47.0 (conflict analysis result) - Only one of these can be installed: laravel/framework[v9.0.0-beta.1, ..., 9.x-dev], illuminate/console[dev-master, v10.0.0, ..., 10.x-dev, 11.x-dev]. laravel/framework replaces illuminate/console and thus cannot coexist with it. - Root composer.json requires illuminate/console ^10.0|^11.0 -> satisfiable by illuminate/console[v10.0.0, ..., 10.x-dev, 11.x-dev (alias of dev-master)]. - Root composer.json requires laravel/framework 9.* -> satisfiable by laravel/framework[v9.0.0-beta.1, ..., 9.x-dev].
